Twelve years ago Flora's mother Ingrid disappeared, vanishing from a Dorset beach, presumed drowned. Everyone - especially her sister and father Gil - believes Ingrid is long dead. Everyone, except Flora.

So when she hears that her father has had an accident, and is insisting that he saw his wife, Floral rushes home. But the answers she seeks are nowhere to be found - only further questions. Who did Flora’s father actually see that day? Why is his house filled with towering piles of books? And might the letters hidden within them hold the truth behind her parents’ extraordinary marriage? 

From the Costa Award-winning, Women's Prize-Shortlisted author of Unsettled Ground.
